curved `guide-Ways 1l extending over the top oi" the Cabinet7 the vertical portion o'l said `uide-ways extending from the bottoni of lthe cabinet upwardly to the top ol' the standards, being' formed by the angle bars G and the walls ot the recesses 55. The standards are also provided with vertical ribs l2 haring a4 coveringl of sheet metal 13 between which and the inner edges ot the angle bars 6 the flexible door olf the cabinet. is adapted to slide. This door is composed ot a series oi' sheet metal sections jl-L'C. One longitudinal edge ot each section is folded inwardly and upwardly upon itself to 'liorin a double thickness running` lengthwise of the section. The edge. is'then bent inwardly to Ytorni a [lange 16 and downwardly 'formino' a liangge 1T, aA rib 18 at the extremity oi the lange 1T being inwardly and upwardly turned, forniing a hook-like projection on the section extending troni end to end thereo'l., a narrow gap or openingf being lorined between the rib 18 and the part l5. The other longitudinal edge ol" the section is provided with an inwariilly turned flange 19 terminating in aY downwardly turned lip 20 that is adapted to enter the gap between the parts l5 and 18 and interlock with the flange 17 and the lip 18, and thereby hold the two abuttingl sec tions together while allowingu theni to rockedgewise upon one another. This connection between the sections will be concealed from the 'ront ot the cabinet and will so break the joint. between the abutting sections that the entrance oi dust and dirt through the door will be prevented.

ln assembling; the sections, the flanged ends are interlocked by engaging the flange on one edge of a section with the flange on the adjacent edge ot 'the abutting section and moving` them longitudinally one upon the other. The. sections bear on the rib 12 of the upright standards in their vertical movement and in making the turn at the top oi the cabinet they will ride on the edge of the castings 10, beine' held in place thereon by the curved sections olv the angle. bars.

)is av metallic door oit this type would be quite heavy.y l prefer to provide counterbalanees therefor comprising cables 9.1 passing;l over sheaves having weights 23 at one end and attached to ears 2li secured to the lower section of the door. The upward pull on this lower section will engage the tlangre 19 at its upper edge with the flange 1G of the section above and exert a lifting force hereon to hold the door in anyposition in which it may he adjusted. rilhis lower section is also provided with suitable lifting handles Within the cabinet suitable shelves 26 are provided for pies, cakes or different articles which it may be desired to place thereon.

ln Fig. a inodiied construction is shown, which consists in providing` belts 27 mounted on sheavee 28 in the upper part of the cabinet, said holt-S forming anti-friction surfaces on which the door sections may ride and slide. These belts will tal/re the place of the ribbed casting l() in the 'top of the cabinet.

l claim as my invention:

l. The combination, with a casing having curved guideways, of a vertically sliding door therefor composed of a series of' lonlqitudinal sections, cach section having one longitudinal edge inwardly and upwardly tirncd upon itself against the wall of the section and then outwardly and downwardly turned to orrn a flange and terminating in an upwardly projecting? lip7 the other longitudinal edge cil said section being1 inwardly and downwardly turned and having' an end portion to lit between said flange and said upwardly projectinna lip on the edge of the 30 adjacent section, said end rocking in the angle between said flange and'lip and allowing the ends of said sections to accommodate themselves to the curve of said guideways.

2. rlhe combination.y with a casing having` guideways therein, of a door mounted to slide in said guideways and composed oi" a series of longitudinal sections, each section having` one edge inwardly and upwardly turned upon itself against the wall ot the 40 section and then outwardly and downwardly tnrnedto form a iiange and terminating in an upwardly projecting lip, the other longitudinal edge of lsaid section beingin- V7ardly and downwardly turned on the saine 45 side oit the section and terminating in 'an end that is adapted to fit the angle between the flange and iip of the adjacent section and rock in Said angle during the niovenient of the door in said guideways. and counterdoal- ALEXANDER E.
